[Python-Dev] bitwise operations for bytes and bytearray (original) (raw)

Hi!

I'm interested in adding the functionality to do something like:

b'a' ^ b'b' b'\x03'

Instead of the good ol' TypeError.

I think both bytes and bytearray should support all the bitwise operations.

I've never hacked on cpython before. I'm starting by just trying to add xor to bytearray. I have a ByteArray_Xor function that I think should do this here https://github.com/cowlicks/cpython/commit/d6dddb11cdb33032b39dcb9dfdaa7b10d4377b5f

But I'm not sure how to hook this in to the rest of cypython. I tried adding it where bytearray_as_sequence is declared in this bytearrayobject.c file. But that gave me compiler warnings and broke things.

So now that I have this ByteArray_Xor function, how do I make it be bytearray.xor_?

Thanks!
